Murphy water temperature gauge from the 20T Series Switchgage instruments. This range of mechanical gauges has a diaphragm-actuated gauge and features a classic look featuring a stainless steel bezel, black dial and white graphics. The gauge is protected with a steel case and features a tough polycarbonate lens.

Temperature increases cause the fluid in the sensing bulb to vaporize and apply pressure to the diaphragm. This is converted to mechanical movements to operate the water temperature gauge. The pressure port features a pulsation dampener to help eliminate excess movement in the pointer to permit highly accurate readings.

The Murphy 20T series water temperature gauges are suitable for monitoring engine coolant water, as well as for industrial and automotive applications.

Murphy Switchgages have a built in electrical switch which can be used for triggering alarms or shut down devices. In the 20T model the temperature indicating needle acts as one switch pole which completes the circuit when it touches the level set by the adjustable contact.

This water temperature gauge is the Murphy 20T120C-7M, which measures from 50°C - 120°C and comes with a 7 metre long capillary. This capillary contains a 5/8 - 18 UNF union nut and is supplied with a 1/2" NPT adaptor nut as standard.
